Setting up Neptune Fetcher

Install neptune-fetcher:

pip install -U neptune-fetcher

Set your Neptune API token and project name as environment variables:

Linux

In your .profile or other shell initialization file, use the export commands:

export NEPTUNE_API_TOKEN="h0dHBzOi8aHR0cHM.4kl0jvYh3Kb8...ifQ=="

export NEPTUNE_PROJECT="workspace-name/project-name"

macOS

In your .profile or other shell initialization file, use the export commands:

export NEPTUNE_API_TOKEN="h0dHBzOi8aHR0cHM.4kl0jvYh3Kb8...ifQ=="

export NEPTUNE_PROJECT="workspace-name/project-name"

Windows

1. Open a terminal app, such as PowerShell or Command Prompt.

2. Paste the setx commands and press Enter:

   setx NEPTUNE_API_TOKEN "h0dHBzOi8aHR0cHM.4kl0jvYh3Kb8...ifQ=="

   setx NEPTUNE_PROJECT "workspace-name/project-name"

3. To activate the change, restart the terminal app.

Optionally, add the variable in Settings → Edit the system environment variables.

Jupyter Notebook

In notebooks for your personal use, set credentials with magic commands:

%env NEPTUNE_API_TOKEN=h0dHBzOi8aHR0cHM.4kl0jvYh3Kb8...ifQ==

%env NEPTUNE_PROJECT=workspace-name/project-name

In shared notebooks, it's more secure to use the os and getpass libraries:

import os
from getpass import getpass

os.environ["NEPTUNE_API_TOKEN"] = getpass("Enter your Neptune API token: ")
os.environ["NEPTUNE_PROJECT"] = "workspace-name/project-name"

Note that these don't persist when the notebook kernel is terminated. You must declare the variables again if you restart the notebook.

Google Colab

In Colab notebooks for your personal use, set credentials with magic commands:

%env NEPTUNE_API_TOKEN=h0dHBzOi8aHR0cHM.4kl0jvYh3Kb8...ifQ==

%env NEPTUNE_PROJECT=workspace-name/project-name

In shared Colab notebooks, it's more secure to use the os and getpass libraries:

import os
from getpass import getpass

os.environ["NEPTUNE_API_TOKEN"] = getpass("Enter your Neptune API token: ")
os.environ["NEPTUNE_PROJECT"] = "workspace-name/project-name"

Note that these don't persist when the notebook kernel is terminated. You must declare the variables again if you restart the notebook.

Working with multiple projects

To change the token or project, you can set the context directly in the code. This way, you can set the project for individual fetching calls or globally for your session.

To start using the API, import the alpha module:

import neptune_fetcher.alpha as npt
